Abstract

Objective: To examine the long-term (three or more years) effectiveness of the volunteer-delivered CHIP intervention.

Design: Cohort study

Setting: Hawera, New Zealand

Participants: Of the total cohort of 284 individuals who self-selected to complete the CHIP lifestyle intervention between 2007 and 2009, 106 (37% of the original cohort, mean age = 64.9±7.4 years, range 42-87 years; 35% males, 65% female) returned in 2012 for a complimentary follow-up health assessment (mean follow-up duration = 49.2+10.4 months).

Intervention: 30-day lifestyle modification program (diet, physical activity, substance use and stress management) delivered by volunteers in a community setting.

Conclusions: Individuals who returned for follow-up assessment and entered the CHIP lifestyle intervention with elevated risk factors were able to maintain improvements in most biometrics for more than three years. The results suggest that the community-based CHIP lifestyle intervention can be effective in the longer-term, even when delivered by volunteers.
